He worked as an assistant professor at the University of Latvia where he delivered lectures in the courses such as theoretical mechanics, orbital theory, celestial mechanics, practical analysis and descriptive geometry.[2] He also taught at the University of British Columbia from 1949 until 1974.[3]
